In 2011, Valentine married writer and barrister, Dan Fritz. They have two children together. On 26 October 2022, Valentine announced that she and Fritz were divorcing. She also announced that she would be changing her surname to "Valentine", her
mother's maiden name, saying that "going back [to my father's family name, rather my mother's original family name] felt emotionally regressive, stunting, depressing and quite frankly, anti-feminist." ==References==
